M i/rnnclioJfVd Utfa. n.sp. (Fig\ 43.) 



IMacldsh brown, nuirgins and suture slightly diluted with 

 red ; appendages pale tastaneous, but tibiae and antennae (ex- 

 cept basal and apical joints) somewhat dai'ker. With moderately 

 dense and rather long straggling hairs ; under surface and 

 appendages moderately pubescent. 



Head strongly transverse between clypeal suture and neck, 

 but including mandibles longer than wide ; densely and rather 

 coarsely punctate ; labrum more than twice as wide as long ; 

 punctures sparser and smaller than on rest of head. Antennae 

 almost extending to hind coxae, first joint lightly curved ; 

 slightly longer than third, and distinctly longer than second, 

 second to fifth subcylindrical, fourth slightly longer than fifth 

 and slightly shorter than third, sixth slightly shorter than 

 fifth, seventh slightly wider but no longer than sixth, eighth 

 the width of seventh but slightly shorter, ninth and tenth 

 slightly larger and feebly transverse, eleventh slightly wider 

 than tenth, but very little longer except on one side where it 

 is produced into a moderately acute point. Prothorar rather 

 strongly convex, scarcely tw'ice as wide as long, sides strongly 

 rounded, apex decidedly narrower than base and gently in- 

 curved to middle, stria on each side strongly impressed and 

 marking off a flattened outer portion ; punctures fairly numer- 

 ous but very small. Elytra cordate, scarcely once and one-half 

 as long as wide ; with fairly strong punctures in feeble striae ; 

 interstices with very feeble punctures, the suture moderately 

 raised posteriorly. Length 3 mm. 



Hab. — W. Australia : Bridgetown, from an ants' nest (A. M. 

 Lea). 



The four front tarsi of the ij\)Q are somewhat inflated, but

 probably a male.
